DeepSeek Unveils V4-Pro and V4-Flash, Accelerating the US-China AI Showdown
DeepSeek released its latest chatbots, DeepSeek-V4-Pro and V4-Flash, claiming strong maths and coding performance and positioning them as open-source rivals to OpenAI and Google, with V4-Pro only slightly behind Google’s Gemini 3.1-Pro for knowledge and marginally trailing OpenAI’s GPT-5.4; the Flash version offers faster responses at lower cost. The rollout underscores the ongoing US–China AI race amid privacy and censorship concerns that led to bans on DeepSeek-R1 in several countries, while the Stanford AI Index 2026 notes China leads in publications, citations, patents, and industrial deployments despite the US producing more top-tier models.
